Possibly in history through the two world wars but Europe today has many benefits. Being the UKs closest geographical ally and membership in the EU means that a closer !@#$%^&*ociation would aid trade and exchange of various other !@#$%^&*ets, for example labor which is good for the economy. Secondly a more united europe would act as a larger world power and rival the US giving Europeans a say in world affairs thus improving the position of the UK in the world political stage. You claim that the EU history is worse then the US, Are you referring to world wars, division over Iraq or other history? As far as spain goes i am not sure why, Iraq is often quoted as a reason for terror attacks but as I have stated before, there is a battle against extremism within a nations own society which must also be fought, perhaps more so then those in the middle east given most attacks in the UK come from those born there.
